Wayne 5-layer line for blown/cast film

Wayne Machine & Die Co., has sold a combination five-layer Yellow Jacket laboratory blown and cast film line to the Advanced and Applied Polymer Processing Institute, a processing and research center in Danville, Va.

The line is based on new die technology that can produce both five-layer blown and cast film. The Totowa, N.J., firm said the machine is ideal for fast development of multilayer structures for testing, using small amounts of raw material. It can turn out up to 12-inch lay-flat blown film and 8-inch-wide cast film.

The machine uses a blown film stack die and a feed block and cast film die, both with five layers.

The line consists of three Yellow Jacket extruders with a screw diameter of 1 inch and a length-to-diameter ratio of 24-1.

Wayne Machine supplied the entire line, including takeoffs for the blown and cast film and a torque-controlled winder.
